Importiamo braccia, esportiamo cervelli: fa male dirlo, ma il declino del Belpaese si fonda su questo scambio. A sua volta indotto dalla nostra incapacità di valorizzare il merito. E dalla nostra difesa a oltranza del parassitismo e delle rendite di posizione
The first Bitcoin paper was first released in 2008. My excitement about the potential of blockchain technology has been building ever…
Have you heard of the Bitcoin Lightning Network? It is a proposal that claims that:
There are plenty of file sharing utilities on the web. Some of them are CLI-based, and some of them are GUI-based. Some of them are free, and some of them are paid. When it comes to share or transfer large files from command line over Internet, there are only a few.
One of them is Transfer.sh. No, it isn’t a script, it is a website. It allows you to share files over Internet easily and quickly. You don’t need to install anything except cURL or wget. Most of the Linux distributions comes preinstalled with those utilities, so you don’t need to install anything, really.
Most Python developers have written at least one tool, script, library or framework that others would find useful. My goal in this article is to make the process of open-sourcing existing Python code as clear and painless as possible. And I don't simply mean, "create GitHub repo, git push, post on Reddit, and call it a day." By the end of this article, you'll be able to take an existing code base and transform it into an open source project that encourages both use and contribution.
While every project is different, there are some parts of the process of open-sourcing existing code that are common to all Python projects. In the vein of another popular series I've written, "Starting a Django Project The Right Way," I'll outline the steps I've found to be necessary when open-sourcing a Python project.
Mathematics is all around us, and it has shaped our understanding of the world in countless ways.
In 2013, mathematician and science author Ian Stewart published a book on 17 Equations That Changed The World. We recently came across this convenient table on Dr. Paul Coxon’s twitter account by mathematics tutor and blogger Larry Phillips that summarizes the equations.
Our New Year’s guide to hacker-friendly single board computers turned up 90 boards, ranging from powerful media playing rigs to power-sipping IoT platforms.
Community backed, open spec single board computers running Linux and Android sit at the intersection between the commercial embedded market and the open source maker community. Hacker boards also play a key role in developing the Internet of Things devices that will increasingly dominate our technology economy in the coming years, from home automation devices to industrial equipment to drones.
This year, we identified 90 boards that fit our relatively loose requirements for community-backed, open spec SBCs running Linux and/or Android. This is up from 81 boards in our similar catalog of hacker boards, posted June 1, which was followed later that month by a survey in which readers picked their favorite boards. A year ago in our New Year’s catalog we showcased 64 boards, up from 53, 40, and 32 entries in our previous reports.
Our annual winter round-up does not include a reader survey, which acts as a mid-year update, but below you will find individual summaries of all 90 SBCs with the most recent prices and updates. We also supply links to LinuxGizmos coverage and project websites, plus an extensive comparison table of major features of all 90 boards.
Stacer is an open source app created to better optimize your Linux PC in the sense that it packs quite the list of features you’d normally expect from an
"When you are a Linux power user, it is always mandatory to master using the command-line, since using commands to control the system offers a system user more power and control over the Linux system.
Therefore, for System Administrators and also other system users who love to operate from the terminal, this comes along with spending so much time on the terminal, which to many is not so interesting, even considered to be boring. And, just to do away with the terminal boredom, and dive away from the commands a little, you can keep your self entertained with some Linux terminal games, that is if you love playing games."
When trying to access scientific papers, there are now so many alternative access strategies, that the well-informed scholar may not even notice much of a difference.
In this article, we shall review some of the best Markdown editors you can install and use on your Linux desktop.
What has 21 million lines of code, 4000 contributors, and more changes per day than most software projects have in months, or even years? The Linux kernel, of course. In this video, Greg Kroah-Hartman provides an inside view of how the largest, fastest software project of all absorbs so many changes while maintaining a high level of quality and stability.
FriendlyARM launched an $8 open source, 40 x 40mm “NanoPi Neo” SBC that runs Ubuntu Core on a quad-core Allwinner H3. It's Ethernet-ready, but headless.
Just when you thought you’d heard, read and seen absolutely everything there is to about QR codes, along comes this little story to make you sputter in your corn flakes. Earlier this month, the craft-store chain Michael’s was hit with a lawsuit for the use of QR codes in its circulars by QR code company Neomedia, according to 2DCode.com. Um…and …
Part 1 of 2: "The Road to Superintelligence". Artificial Intelligence — the topic everyone in the world should be talking about.
script
is an open source tool that makes a typescript of everything displayed on your terminal. It is useful for students who need a hardcopy record of an interactive session as proof of an assignment, as the typescript file can be printed out later with lpr.
Everything between the script and the exit command is logged to the file. This includes the confirmation messages from script itself (unless the -q flag is used). Everything between the script and the exit command is logged to the file. This includes the confirmation messages from script itself.
Recorded shell sessions can be shared using online services. The advantage of sessions recorded in this format from the usual screencasts is that shell instructions can be easily copy/pasted from the player screen.
Useful command:
script --timing=time.txt script.log
and to replay
scriptreplay --timing=time.txt script.log
See also the nice -d
(divisor, speeds up playback) and -m
(max delay in playback) options for replay.
